2 efinition YNASIM is a user-friendly ship simulator that utilizes ship maneuvering characteristics to faithfully reproduce ship motion in the presence of: winds waves currents obstacles other ships...etc. Multi-threading enables simultaneous simulation of multiple ships. An auto-pilot following traffic regulation enables traffic simulation in harbors and waterways YNA Status indication dials Capabilities YNASIM incorporates state of the art models of ship motion and is capable of executing real time simulations of ship maneuvers in complex environments in real or accelerated time. YNASIM employs modular mathematical models for the various components of the ship (hull, propellers, rudders, thrusters) and environmental effects (wind, current, waves) and waterways (bottom, pier walls) to achieve a sophisticated and faithful mathematical model for ship maneuvers. These models are based on collective experience resulting from the development of several ship maneuvering software. YNASIM runs on a Windows operating system and has a user-friendly interactive graphic interface. It achieves capabilities on par with expensive stand-alone full-mission simulators.

3 SIM Applications YNASIM is suitable for the following applications: Training of master pilots Traffic safety evaluation in harbors Safety study of vessel types, traffic densities, waterway geometries Harbor structures design Navigation channels design Port traffic planning Marine/navigation regulation development Tug operation optimization Ship control panel Route properties panel YNASIM includes the following: Advantages & Features Ship definition panel Advanced mathematical modeling of ship maneuvering hydrodynamics Environmental effects: wind, wave, current, bathymetry,... User input ship data file Ship characteristics: type, geometry, twin screw, bow/stern thrusters, tugs,.. Simulation of IMO standard ship maneuvers Autopilot with collision avoidance Configurable preplanned routes and ship schedules Harbor/waterway system safety metric Fuel consumption calculation Tug operation simulation by a user controlled tugboat and/or by tabulated force vectors Human errors and delays Graphic User Interface with user control input through a keyboard, a mouse, and a joystick Technical support and flexible customization

4 YNA SIM Simulation Modes YNASIM has three basic simulation modes: User controlled mode: in YNASIM the user controls the rudder, the engine, and any lateral thrusters through a graphic control panel to simulate the navigation of a ship. Standard maneuver mode: YNASIM can simulate a ship performing one of the classical maneuvers (turning circle, zigzag, spiral) recommended by the International Maritime Organization (IMO) for certification and evaluation of ship hydrodynamic characteristics and maneuverability. Computer controlled navigation mode: YNASIM can model ship traffic in the open ocean or in a restricted environment. The behaviors of the auto-piloted ships along prescribed routes in the simulation are based on the U.S. Code of Conduct of Vessels. Traffic central parameters can also be adjusted by the user. Session recording and replaying Auto-Pilot navigation rules

5 Environment efinition Environmental conditions can be user input and drawn with a set of tool bars or can be read from an environmental data file.

Technical report nsf, October Parallel evelopments The hydrodynamic characteristics implemented in YNASIM can be updated using the results from advanced computational hydrodynamics codes such as YNAFLOW s 3YNAFS, which can handle nonlinear, large amplitude vehicle motion, high waves, surf zone waves, etc. An additional major characteristic of YNASIM is the incorporation of a multiobjective system identification technique to determine the vehicle parameters. This enables the autopilot to adjust the vehicle parameters based on feedback from ship response to pilot commands.
